The PWM (D/A) module has the following registers. The PWM (D/A) registers are assigned to the
same addresses with other registers. The registers are selected by the IICE bit in the serial timer
control register (STCR). For details on STCR, see section 3.2.3, Serial Timer Control Register
(STCR).
Note: The same addresses are shared by DADRA and DACR, and by DADRB and DACNT.
